GW-40F Steel Bars Rebar Bending Testing Machine

Product Introduction

I. Overview

The Rebar Bending Testing Machine is specialized Machine used to perform cold bending tests and plane reverse bending tests on steel reinforcement bars (rebar). Its main technical parameters comply with the standards:

 

ISO 6935-2:2019 Steel for the Reinforcement of Concrete – Part 2: Ribbed Bars

ISO 10065:1990 Steel Bars for Reinforcement of Concrete – Bend and Rebend Tests

GB/T 1499.2-2018 Steel for the Reinforcement of Concrete – Part 2: Hot Rolled Ribbed Bars

YB/T 5126-2003 Test Methods for Bending and Reverse Bending of Steel for Reinforced Concrete

 

This Machine is capable of performing 180° bending tests (cold bending) and plane reverse bending tests (i.e., bending 90° forward, then rebending 20° in the opposite direction), as specified in the above standards.

It is an ideal device for steel manufacturers and construction units to inspect the bending and reverse bending properties of rebar.

The machine features a compact structure, intuitive angle display, simple operation, easy maintenance, smooth operation, and safe performance.
